Marathon Oil Is Now Independent Upstream Company


Marathon Oil Corporation said Friday it has completed the spin-off of Marathon Petroleum Corporation, making Marathon Oil an independent upstream company.

Marathon Oil has a strong and geographically diverse portfolio of assets leveraged to crude oil production. The Company will continue to be based in Houston.

“This is an exciting day and a major milestone in the nearly 125-year history of Marathon Oil Corporation,” said Clarence P. Cazalot Jr., Marathon Oil’s chairman, president and CEO. “As an independent upstream company, we have the capacity to perform at a higher level by focusing on strategic priorities while providing greater transparency for investors. Operationally, we’re poised to capitalize on a broad base of opportunities by exhibiting the speed, agility and flexibility of an independent and retaining our proven ability to accomplish large and technologically challenging projects. What isn’t going to change is our focus on long-held core values of health and safety, environmental stewardship, honesty and integrity, corporate citizenship and a high performance team culture. Together, these attributes create the foundation for a strong, competitive Company with a goal of continuing to deliver long-term value growth for our shareholders.”

With this change and effective July 1, Cazalot becomes chairman of the board of Marathon Oil Corporation in addition to his responsibilities as president and CEO. Additionally, David E. Roberts Jr. takes on the newly established role of executive vice president and chief operating officer. Janet F. Clark will continue in her role as executive vice president and chief financial officer.

Bowzer, North America Production Operations; Steven P. Guidry, Business Development; Bryan J. Roy, Drilling and Completions; Gregory S. Sills, Upstream Developments; and Gretchen H. Watkins, International Production Operations.

To effect the spin-off, Marathon Oil shareholders received one share of MPC common stock for every two shares of Marathon Oil common stock held on the record date of June 27, 2011. MPC is now an independent, publicly traded company, in which Marathon Oil retains no ownership interest.


Effective today, Marathon Oil has adopted a new corporate logo – an abstracted tri-color wave – that symbolizes the momentum resulting from its exploration and production activity as well as the drive and innovation of the Company’s employees. The new branding is reflected on the new corporate website, on Twitter @MarathonOil and on Flickr, Linkedin and StockTwits.
